Abstract: A dishwasher, dishwasher sprayer, and method of spraying utilize a tubular spray element with multiple selectable spray patterns that can be used during a wash cycle. In some instances, multiple selectable spray patterns may be supported through the use of a multi-walled tubular spray element having concentric wall sections that are movable relative to one another to selectively activate one or more apertures and thereby modify a spray pattern emitted by the tubular spray element. In other instances, multiple selectable spray patterns may be supported through the use of a multi-chamber tubular spray element in which different sets of apertures are in fluid communication with different chambers in the tubular spray element and flow is selectively controlled to one or more of the chambers.

Abstract: A method of washing objects in a dishwasher having upper and lower spray arms within a wash chamber and a sump filter. Wash liquid entering a sump from the wash chamber to be recirculated by a pump is filtered the filter to prevent soils from entering the sump and being recirculated. When the lower spray arm is operating, wash liquid is directly sprayed onto the filter from a clean-out nozzle on the lower spray arm to clean soils off the filter and prevent the filter from clogging. During a pre-wash cycle and at least one pre-rinse cycle, wash liquid is continuously sprayed from only the lower spray arm to prevent the filter from clogging when heavy soils are removed. During a wash cycle and at least one rinse cycle, wash liquid is alternately sprayed from the lower spray arm and the upper spray arm when the heavy soils have already been removed and it is less likely the filter will become clogged.
